Rework commit b726974 to avoid exposing setters that would permit anyone
to change Spring Boot's defaults. Also, since these are configurers of a
specific instance, they should be named accordingly.

There's a long cycle when Spring Data REST, Data JPA and Actuator
are used in an app that retrieves its DataSource from JNDI. The cycle
is:
- WebMvcAutoConfiguration
- HttpMessageConverters
- MappingJackson2HttpMessageConverter (needs an ObjectMapper)
- SpringBootRepositoryRestMvcConfiguration
- ObjectMapper
- RepositoryResourceMappings (part of a custom Jackson module)
- Repositories
- EntityManagerFactory (Triggered by application's Spring Data JPA repository)
- HibernateJpaAutoConfiguration
- JndiDataSourceAutoConfiguration
- MBeanExporter (Used to prevent export of DataSource MBean that's already in JMX)
- EndpointMBeanExportAutoConfiguration
- ObjectMapper (Used to format JSON produced by the exported endpoints)
Spring Data Rest caused the ObjectMapper to depend on JPA. JPA depends
on the DataSource. JnidDataSourceAutoConfiguration depends on the
MBeanExporter. Actuator's MBeanExporter requires an ObjectMapper to
produce JSON strings.
This commit breaks the cycle by making JndiDataSourceAutoConfiguration
access the MBeanExporter lazily. Rather than using `@Lazy`. which does
not work with `@Autowired(required=false)`, the application context
is injected and the MBeanExporter is retrieved manually when it is
needed.

Spring Boot supports the automatic configuration of an additional
HazelcastInstance if one already exists and an explicit property has been
set to use a different configuration for caching. So three cases are
supported really: no `HazelcastInstance` exists so we need to create one
anyway or an `HazelcastInstance` already exists; in that latter case, we
should either reuse it or create a new one.
Unfortunately, the conditions that checked those three use cases were
not ordered consistently and we could easily get in a situation where
both conditions were evaluated.
This commit makes sure that we first check if an `HazelcastInstance`
exists and then (and only then) we create the missing `HazelcastInstance`
used for caching. The tests have also been improved to validate the
proper `HazelcastInstance` is used for caching.
Closes gh-5181
Previously, if one wants to create a custom `JmsListenerContainerFactory`
or `RabbitListenerContainerFactory`, a bunch of code from the auto-
configuration must be duplicated.
This commit introduces two services to configure such factory for JMS
and AMQP with the same sensible defaults that were applied by the
auto-configufrations.
Closes gh-5138
Previously, WebSocketMessagingAutoConfiguration added a single
additional converter. This was a MappingJackson2MessageConverter
configured with the auto-configured ObjectMapper.
AbstractMessageBrokerConfiguration places additional converters before
any of the default converters. This meant that the auto-configuration
had the unwanted side-effect of changing the ordering of the
converters. A MappingJackson2MessageConverter was now first in the
list, whereas, by default, it's last in the list after a
StringMessageConverter and a ByteArrayMessageConverter.
This commit updates WebSocketMessagingAutoConfiguration so that it
switches off the registration of the default converters and registers
a StringMessageConverter, ByteArrayMessageConverter and
MappingJackson2MessageConverter in that order. A test has been
added to verify that the types of these three converters match
the types of the default converters. A second test that verifies
that String responses are converted correctly has also been added
alongside the existing test that verified the behaviour for JSON
responses.

DriverClassNameProvider is unused but was probably restored by a merge
commit at some point. It wasn't obvious and updated that class rather
than `DatabaseDriver`.
This commit updates `DatabaseDriver` and deletes
`DriverClassNameProvider`.
Closes gh-5076
Update `ResourceBundleCondition` to only enable the messages source
if `messages.properties` (and not `messages*.properties`) exists. This
operation is much faster that performing a pattern match since a full
jar entry scan is not required.
Since adding `messages.properties` is good practice and this change
allows us to delete the custom `PathMatchingResourcePatternResolver`
it seems like a fine compromise to make.

When a Jersey app is deployed to a standalone container, Jersey’s
ServletContainerInitializer will run and register a servlet for a class
annotated with @ApplicationPath. If Jersey’s ServletContainerInitializer
runs before Spring’s, this servlet will take precedence over the
servlet registered by JerseyAutoConfiguration and will therefore not be
configured with any init parameters specified using spring.jersey.init
For the case where Jersey’s SCI runs first, this commit updates
JerseyAutoConfiguration to examine the servlet context for an existing
registration of Jersey’s servlet (Jersey names the registration using
the fully-qualified name of the ResourceConfig subclass). If a
registration is found its init parameters are configured using the
configuration provided by spring.jersey.init.
For the case where Spring’s SCI runs first, this commit updates
JerseyAutoConfiguration so that it names its registration using the
fully-qualified name of the ResourceConfig sub-class. This allows
Jersey’s SCI to find the existing registration rather than attempting
to configure its own.

While Flyway's `MigrationVersion` is a String value, a simple "0" is
also a valid number. When such value is not wrapped in YAML, an integer
is injected rather than a String which leads to a failure as we can't
convert it.
This commit updates the `StringToMigrationVersionConverter` to also
supports conversion from a Number. This is a convenience for users
using YAML for configuration

The same initializer will receive multiple ContextRefreshedEvents
when their is an application context hierarchy. This commit updates
the initializer to correctly handle multiple ContextRefreshedEvents
and only act upon the first that it receives.
See gh-4871
This commit is a continuation of the changes made in b85b608. It
addresses an additional problem when testing applications where two
contexts are refreshed in quick succession. In this scenario, it
was possible, theoretically at least, for the first context’s background preinitialization to still be in progress and creating loggers when the
second is refreshed and resets the logger context.
This commit updates BackgroundPreinitializer so that, upon receipt of
a ContextRefreshedEvent, it waits for preinitialization to have
completed. In the scenario described above, this ensures that
preinitialization has completed before the call to refresh() for the
first context returns, thereby preventing it from running in parallel
with the refresh of the second context.
Closes gh-4871
If Both Hazelcast and Hibernate are available, Spring Boot takes the
opinion that Hazelcast can be used for 2nd level caching and therefore
need to start before Hibernate.
Unfortunately, some users require Hibernate in some of their hazelcast
use case so the link is actually reversed. One way for such user is to
disable the auto-configuration that deals with this link. This class is
now public so that users can locate them and exclude them if necessary.
Closes gh-4960
Previously, BackgroundPreinitializer would kick off preinitialization
on a separate thread in response to an ApplicationStartedEvent. This
work would then race with the logging system being set up in response
to an ApplicationEnvironmentPreparedEvent. When Logback’s being used
this race is problematic. As part of Logback’s setup,
LoggerContext.stop() is called. This calls LoggerContext.reset() which
can fail with a ConcurrentModificationException if another thread tries
to create a Logger at the same time. This is a known bug in Logback [1].
This commit updates BackgroundPreinitializer to respond to
an ApplicationEnvironmentPreparedEvent and to order itself so that it’s
called after LoggingApplicationListener has responded to the same event
by initializing the logging system.

Mongo’s 2.x driver allowed the credentials list to be null, however
the 3.x driver requires an empty list instead. The behaviour of the 2.x
driver is the same whether the client is created with a null credential
list or an empty credential list.
This commit aligns with the requirements of the 3.x driver by ensuring
that we never pass in a null credential list when creating the client.

Webjars locator is a good hint that the resource chain should be
enabled. The sole presence of the library now enables the resource chain
unless the configuration states otherwise.
Closes gh-4403
Previously, MustacheViewResolver would create an InputStreamReader
that wraps the template Resource's InputStream but would fail to close
the Reader. When the InputStream was a FileInputStream, this caused
the resolver to leak file handles.
This commit updates the resolver to close the Reader once the Template
has been compiled, thereby allowing any underlying resources to be
cleaned up immediately, rather than having to wait for the JVM to exit.
Closes gh-4921
This commit completes the changes to consistently used static final
fields for Log instances that were started in ec2f33f9. Specifically it:
- Removes this. when accessing logger fields that are now static
- Renames some fields from log to logger
- Makes some logger fields static

SecurityFilterAutoConfiguration uses SecurityProperties which uses
SessionCreationPolicy from spring-security-config. This commit makes
SecurityFilterAutoConfiguration conditional on SessionCreationPolicy,
thereby preventing a startup failure if spring-security-web is on the
classpath but spring-security-config is not.

Issue #4533 was supposed to make BasicBatchConfigurer public again but
unfortunately only the class visibility was changed. This commit makes

Ensure that Collections.isEmpty() is used to check if there are no
elements in a collections. This is more explicit and can be faster than
calling .size().
Closes gh-4783
Spring Data’s web support includes a handler method argument resolver,
ProxyingHandlerMethodArgumentResolver, that inaccurately claims that it
can handle all interface handler method arguments. This causes problems
for handler methods that take Spring Mobile’s Device as an argument as
the proxied Device instance does not behave correctly.
This commit works around the problem by assigning an order to the
WebMvcConfigurerAdapter that registers Spring Mobile’s argument resolver
with Spring MVC. This ordering ensures that Spring Mobile’s resolver
takes precedence over Spring Data’s for Device arguments.
Closes gh-4163
Extend ElasticsearchDataAutoConfiguration to also configure an
ElasticsearchConverter and SimpleElasticsearchMappingContext both

Google App Engine probits the creation of new threads. This leads to a
failure in BackgroundPreinitializer when the single thread executor
attempts to create its single thread.
This commit enhances the existing fail safety of
BackgroundPreinitializer by catching any exceptions thrown while
creating the executor and submitting the tasks to it. Any initialisation
that has not performed in the background will be performed in the
foreground instead.
